Description

Technical Field

[0001] The utility model relates to the technical field of grain processing equipment, in particular to a simple magnetic separator. Background Art

[0002] A magnetic separator is a device that separates magnetic substances in grain from grain. It is often used in the grain processing industry. A grain magnetic separator is a machine that uses magnetic field force to separate iron impurities from grain. Its main function is to remove iron impurities in grain, ensure the stability and safety of grain quality, and improve the purchasing power and use value of the product. Grain magnetic separators are widely used in grain, oil, feed and other processing and storage industries, and are a very important type of agricultural machinery and equipment.

[0003] According to the search, the utility model patent with patent number CN202222007389.5 discloses a magnetic separator that is convenient for removing iron. The patent designs a convex plate on the roller to make the outer surface of the roller rough, which can adsorb magnetic impurities, increase the adsorption area of ​​the magnetic impurities, improve the adsorption effect, and thus improve the quality of grain.

[0004] However, this patent has defects. Although the relief plate improves the adsorption effect, it means that the magnetic impurities adsorbed on the drum can only be cleaned by a vibrator after the processing is completed. During cleaning, the drum needs to be continuously rotated so that the magnetic impurities can be dropped by vibration, resulting in low cleaning efficiency. At the same time, if too many magnetic impurities are adsorbed in the gaps between the relief plates during processing, when the grain collides with the drum, the magnetic impurities are easily caused to enter the grain for the second time, reducing the effect of cleaning the magnetic impurities.

[0027] Through the above-mentioned structural arrangement, grains fall from the feed port 2 onto the surface of the drum 6. After magnetic separation, the triangular slope inside the shell 1 will guide the falling grains and magnetic impurities to fall toward the two sides of the slope. The grains are discharged from the raw material port 3, and the magnetic impurities are discharged from the impurity port 4.

[0028] Reference Figure 2-3, wherein the magnetic suction cylinder 5 is divided into different parts from the middle, the left side is the magnetic part, the right side is the non-magnetic part, and the surface of the roller 6 is provided with a groove;

[0029] Through the above-mentioned structural arrangement, the grain falls from the feed port 2 to the left side of the magnetic suction cylinder 5. The groove can increase the contact area between the surface of the roller 6 and the grain, thereby enhancing the adsorption effect. The roller 6 will adsorb the magnetic impurities to its surface. At the same time, the driving component 7 will drive the roller 6 to rotate slowly. When the surface of the roller 6 that adsorbs impurities rotates to the side without magnetic force, the magnetic impurities adsorbed on the surface begin to fall off gradually, and then fall along the impurity port 4.

[0030] Reference Figure 1-3 , wherein the driving assembly 7 includes a first motor 71, the first motor 71 is fixedly mounted on the outer side of the housing 1, a pulley set 72 is fixedly mounted on the output end of the first motor 71, and the other end of the pulley set 72 penetrates and extends to the interior of the housing 1 and is transmission-connected to the drum 6;

[0031] Through the above-mentioned structural arrangement, after the magnetic separation work starts, the first motor 71 is started, and the first motor 71 drives the drum 6 to rotate through the pulley set 72 to absorb the magnetic impurities inside the grain.

[0032] Reference Figure 2-4 , wherein the cleaning assembly 8 includes a brush 81, the brush 81 located on the right side of the drum 6 is rotatably mounted on the inner side wall of the housing 1, and a second motor 82 for driving the brush 81 to rotate is fixedly mounted inside the housing 1;

[0033] With the above-mentioned structural arrangement, when the drum 6 starts to rotate, the second motor 82 is started, and the second motor 82 drives the brush 81 to rotate, so as to clean the surface of the drum 6 and sweep away the magnetic impurities that have not fallen off the surface.

[0034] Reference Figure 1-4 The air blowing assembly 9 includes a fan 91, the fan 91 is fixedly installed inside the housing 1, the air outlet end of the fan 91 is connected to a vent pipe 92, the air outlet end of the vent pipe 92 is connected to an air nozzle 93, the air outlet end of the air nozzle 93 faces the drum 6 and is fixedly installed above the brush 81;

[0035] With the above-mentioned structural arrangement, when the brush 81 cleans the surface of the drum 6 , the fan 91 is started, and the fan 91 sprays gas through the vent pipe 92 and out of the air nozzle 93 , thereby assisting the brush 81 in cleaning the surface of the drum 6 .

[0036] Working principle:

[0037] The first step to implement the innovation point:

[0038] Step 1: After the grain is magnetically separated, the grain is poured into the feed port 2. The grain falls from the feed port 2 to the left side of the magnetic suction cylinder 5. The groove can increase the contact area between the surface of the roller 6 and the grain, thereby enhancing the adsorption effect. The roller 6 will adsorb the magnetic impurities to its surface. At the same time, the driving component 7 will drive the roller 6 to rotate slowly. When the surface of the roller 6 adsorbing impurities rotates to the side without magnetic force, the magnetic impurities adsorbed on the surface begin to fall off gradually, and then fall along the impurity port 4.

[0039] Step 2: While the drum 6 is rotating and the second motor 82 is engaged, the second motor 82 drives the brush 81 to rotate, cleans the surface of the drum 6, and sweeps off the magnetic impurities that have not fallen off the surface. When the brush 81 is cleaning the surface of the drum 6, the fan 91 is started, and the fan 91 sprays gas through the ventilation pipe 92 and the air nozzle 93, thereby assisting the brush 81 in cleaning the surface of the drum 6.
